Self-Stratifying Behavior of a Light-Curable Coating Containing Bio-Renewable Materials: Study on the plasticizer type

This study aimed to find the best plasticizer for methacrylated gelatin (GelMA) to develop a well-structured lightcurableself-stratifying coatings using GelMA and acrylated epoxidized soybean oil (AESO). The influences ofseveral solvents including ethanol, glycerin, formamide, acetic acid, and dimethylsulfoxide on the stratificationlevel were evaluated by SEM. It was learned that the performance of solvents can be managed by their solubilityparameter and evaporation rate. Also, the results demonstrated that solvents with higher evaporation rate and lowersolubility parameters such as ethanol and acetic acid could not lead to proper self-stratificatied morphology in agreen GelMA-AESO-based coating
